## Description

- description: Bilayer graphene (BLG) was recently shown to host a band-inverted phase
    with unconventional topology emerging from the Ising-type spin–orbit interaction
    (SOI) induced by the proximity of transition metal dichalcogenides with large
    intrinsic SOI. Here, we report the stabilization of this band-inverted phase in
    BLG symmetrically encapsulated in tungsten-diselenide (WSe2) via hydro- static
    pressure. Our observations from low temperature transport measurements are consistent
    with a single particle model with induced Ising SOI of opposite sign on the two
    graphene layers. To con- firm the stabilization of the inverted phase, we present
    thermal activation measurements and show that the SOI-induced band gap increases
    by more than 100% due to the applied pressure. Finally, the investigation of Landau
    level spectra reveals the magnetic field dependence of the level-crossings on
    the applied field, which further confirms the enhancement of SOI with pressure.
